V4L/DVB (4979): Fixes compilation when CONFIG_V4L1_COMPAT is not selected
- SYSFS: Replaced all to_video_device(cd), video_device_create_file, video_device_remove_file and add the proper checks at create_file - Converted old norm values to V4L2 ones. - Robustness on sysfs hue/contrast/saturation queries. Additional check in order to return 0 if the driver is not opened. - Whitespace cleanups in usbvision-cards.c This patch merges two fixes by Thierry MERLE and Mauro Chehab, and adds additional checks.
